“No, after all…

**Physical reality (all spacetime) began to exist.**

**This article analyzes six evidences,…**

• [Big Bang] [Gravity equations yield a past-bound singularity](/universe/begin#singularity).

• [G.Relativity] [General Relativity's singularity model is true](/universe/begin#relativity-big-bang).

• [BGV theorem] [Any average-expanding space has a beginning](/universe/begin#bgv).

• [2nd Law] [Total entropic decay has not arrived yet](/universe/begin#entropy).

• [General 2nd Law] [Total generalized entropy is not maxed](/universe/begin#generalized-entropy).

• [Philosophy] [Logically, prior events cannot number to infinity](/universe/begin#finite-events).

“Yes, after all…

**The Aguirre-Gratton reversed arrow-of-time model is true.** This is relevant because the model lacks a beginning.

**The Carroll-Chen reversed arrow-of-time model is true.** [See full article.] This is relevant because the model lacks a beginning.

**By way of response**…

• …it implies you're a Matrix brain that *just* formed.

• …it requires a highly improbable bounce stage.

• …it destroys probabilistic reasoning
